Let me tell ya..I assumed i was just low on testosterone since I’m in my 40’s. I was gaining weight quickly, suffered from short term memory loss and was exhausted all day. Had blood work done and turns out my vitamin D level was at a 3! Started taking D supplement and it cured it all. My energy levels went up and I lost 30lbs like it was nothing. And now I can even remember what I ate for breakfast lol. I was amazed at the role it plays on your body.
How much doze I.u. do you take for vitamin d?n how long?
What are supplements for cure?
Wonderful.
im suffering from same and did blood test and doctor said the same thing so rn going for treatment, can you tell us how you lost weight?
@@yangamsonam you lose weight by having self control.
I was 24 when I moved to Canada in 2017.
But, I was born in southern India where the tropical climate plays a big role. I was under the sun almost every day I felt really healthy, never obese, and more active, and it's very rare I got sick.
After experiencing the first winter in Canada which is 5 months of cold weather - I stayed inside all those months. I gained weight, felt sick, and Dehydrated most of the time. And also the diet here in America is so bad. I got to the doctor-prescribed Vitamin D. I'm back on track.
My advice is to go out in the summer - get all you can. All living things in this world need SUN to survive.
Hahahah I'm from Canada and it gets cold there! I'm in Texas now with lots of 🌞
Yes I lived in Canada my whole life so far. The winters are really something else lol. was -40 celsius just a week ago where I live lol
I had a vitamin d and c deficiency. How I knew something was wrong is because my legs constantly hurt and nothing relieved it. My doctor did a vitamin d test found out I was low and though I was on vitamin d my legs still hurt. My chiropractor suggested testing my vitamin c which was also low and now I have no leg pain. Listen to your body people.
fantastic! may I ask if you take vitamin c liposoluble? I take the regular one (that you pee eventually) but I'd like to know if you take the regular one and still got absorbed.
@@AlbionRising I just take the regular one.
Do you know why you were deficient in vitamin c?
@@hayd9785 No, I'm not sure. I'm guessing not enough of it in my diet.
Vitamin C deficiency is insanely rare in modern society, almost no one is going to have that. Especially with all the BS pseudoscience having people taking it all the time.
I was deficient in Vitamin D (my test came back at 11 when the recommended range is 30-100) and didn't realize I was suffering from it until I was put on prescription dosage twice a week. It can effect your energy levels, hair, skin, and nails. I take the prescription dosage once weekly but I'm only just inside that 30-100 range. Vitamins are no joke
My daughter who is 14 was having symptoms of tiredness, liver enzyme’s a little high, fast heart rate. Come to find out, her vitamin D was 14. She is now on a 2 month vitamin D Waffer to. bring up levels then she will take regular supplements for it.
@Cookie Monster i only suffered the exhaustion. I could get a full nights rest and pass out and sleep another 4-5hrs by 2pm. We only checked my levels cause it had never been done before and my primary wanted a baseline.
I got checked a few weeks ago, cause i have bone issues that kept getting worse. The test gave me a 3...i am getting tested this week again after high dosage therapy...i hope this will stop the bone-swelling sooner or later
Wow, the people in this thread who are super low on vitamin D! Make sure you take K with your D every day and take magnesium - super important.
Had it at 10.7. I was tired, nervous, depressed, more anger problems. I also had severe insomnia, sweating during nights until my sheets got really wet. Nightmares. Could not bear it any longer and got medical help I needed. Now I have 48.6, and I will never ever ever again avoid sunlight because pAlE sKiN sO gOOoThIc. Glad summer is almost here, will befriend our Sun so I do not have medical problems anymore.

Great! Thanks for answering!
@@kevinyonan2147 maybe, i just like it this way, easier for me to remember. Thanks anw.
@@theanatomylab love your guys content as always.
@@kevinyonan2147 yup, that’s how I aid in memorization. I think we all learned that from school days, lol.
I'm preparing for NEET exam and these videos are really helping me to understand the concepts so clearly. I couldn"t go to lab or i can't attend classes so this channel is helping me through a lot.. I am really thankful. My goal is to become a Doctor I'll comment again on this channel when i achieve my Goal🥺
EDIT : I watch this channel to get the basics understand of what my textbook has i only take a part of it. and not try to understand everything is see in the video. so it doesn't affect my knowledge in anyway.. I know these are some advanced portion of what iam studying now but these videos enhance my memory in storing what my textbook teaches me.. that's the only reason that I'm here.. hope everyone understand
We love hearing things like this. Thank you for the comment and good luck on your goal!
@@masoommahi Thank you
All the best!!
@@sundaragnanasekar2379 TQSM
Good luck.. so awesome you wanna be a Dr 💙
Four fat soluble vitamins are D, E, K, A. "Deka" means blanket in my language so I can never forget it, but also it helps that I know their chemical structures and properties 😆
In New Zealand we use to have a department store called DEKA.
YEA exactly in my country SLOVAKIA.
DEKA (blanket) or ZADEK without Z ( ass) :D
No you don't
In my language it’s an informal way of saying “it’s big” (deka, dekai). 😂
@@whika070 Funny, in Germany we have supermarkets called Edeka and is used to remember that.
I've been an ileostomate for 22 years now (I don't have a colon.) I've been diagnosed with anxiety, PTSD, and depression. I had no idea how vitamin D could effect your mental health. I think I need to get some blood work done to see if vitamin D might help with it. Thank you for putting this video out.
Hi sweetheart please read my comment about how this has affected my health- I too have had a lot of surgery on my bowel and also suffer a raft of problems with my health ( rheumatoid arthritis- fibromyalgia- chronic pain and fatigue) to mention a few !- but I have also suffered severe depression and anxiety- and I have always assumed that it was my physical health impacting on my mental health- but since having a diagnosis of very low vitamin D- I have come to understand that this can also cause mental health issues?- so my advice is simply this- YES GET CHECKED OUT!- I hope to have a chance to talk to my dr soon to find out how this low vitamin D has happened- but for now I am just hoping that the extremely high vitamin D capsules will work their magic!-( and I am also trying to get more exposure to sunshine and also making sure that I make good dietary choices etc- ?) Tbh - I am sure that I have had to make good choices anyway due to my health- but I have to be open minded in order to improve!? - I wish you good luck sweetheart 🥰
@@MsPopeye65 Thank you so much for sharing this with me. I'm having blood work done tomorrow and I can't wait to see how it turns out.
I had blood work done and I am low on Vitamin D. I am also going through a similar thing with a passing of a family member. Stay Strong❗️🙏
@@iUnicornTv It's unbelievable that this seems to be a common issue. Doctors should look a little closer when they have a patient presenting with these symptoms. I'm sorry for your loss. I lost my sister 5 years ago and it left me heartbroken.
@@sharonzona4346 good luck sweetheart- hope all goes well with you- keep me updated on how you get on - thinking of you 🥰
I love that you and Justin are doing this together. Always awesome teachers. So happy for you guys.
I love these videos. I’m 71. Back in the day, I was premed. I enjoy staying mentally active. I home schooled my son. Now I hope I can make science fun for my grandkids. Thank you so very much 🧐.
Before lockdown i was already living a stangent lifestyle inside my home due to being jobless and lockdown made it worse. My health declined, lost 13 kg without even trying, 2tooths got rct, hairfalls and much more.
All this made me realise one important thing, that's more important than proper diet, that is, just move your body, no matter what just don't lie down and rest for long, it'll ruin you. It's not a coincidence that we get vit d from sun, if you move your asss, you're gonna get this vit while being exposed to sun while moving. Human body is very smart. You don't need to add anything extraordinary just eat normal and be active always.
You are guys amazing!! The super complex mechanisms of our wonderful body are so beautifully explained that a layman can easily understand. I can see in the comment section that you have changed so many lives by making things easy for people and helping them ace their exams. Thank you for creating this channel !!
When we first went on lock down for COVID, my feet, hands and legs all of a sudden started numbing. I automatically thought diabetes. My blood was tested and turned out my vitamin D level was at 13. My doctor prescribed me vitamin D and the numbness went away. I take vitamin D regularly now.
We’re suppose to get 90% from the sun and it’s actually a hormone. Supplement good too but too much can be toxic and blood levels can get toxic.
With k2?
Oh what thats happening to me now numb hands and feel I was told 3 years ago I was deficient guess I better thanks some vitamin D and go for a walk in the sun😂
You need k2!!
Covid drains vitamin d
What’s crazy is that taking in too much vitamin d through supplements can actually severely damage someone’s liver due to it being fat soluble, someone I know actually got a fatty liver from it.
Yeah, he being a drunk and eating a lot of junk food didn't have anything with that, just a vitamin..
😬 Definitely don't want to over do it. Sorry to hear about your friend.
Was it D3, or D2
Vitamin D2 and K1 might not be healthy
Fancy meeting you here. I've seen you on a variety of RUclips channels. Hope you're having a good day.
It can also give you the shits…..lol
You two guys are INCREDIBLE TEACHERS!!! Thank you so much for this series!💝
Great job! I love how you went over the hormones and the 'down stream' effects of each one. If your liver is damaged it may not perform this properly, same for your kidneys. It's important to keep all your organs as healthy as possible because they all work together. ❤❤
This question arises in my mind for a long period of time. Thank you sir for explaining it briefly. I understood with joy by watching your videos.
I have converted my daughter to watching these videos .. thank you so much for the way you present them. She is 15 and has a keen interest in forensic pathology. For many years I was a morgue assistant , had I been given the chance i would have loved to have been a mortician ..
Perhaps you should do it?
That's awesome this channel is so interesting and informative.. so cool that you were a morgue assistant may I ask what type of tasks you were asked to do.. that is so very interesting to me
Watch Catlin the morticians videos
Мaybe it will be interesting for your daughter to read this book - All That Remains: A Life in Death by Sue Black. She's professor of anatomy and forensic anthropology and writes about her work and how forensic science has developed through the years.
Your job needs a strong stomach or a good spiritual grounding. Modern research on Near Death Experience by Raymond moody, reincarnation memories by Ian Stevenson/Jim trucker and past lives regression by Brian Weiss all independently but coincidentally show that our consciousness survive death, we live many lives and our thoughts and actions matter in the hereafter.
So be kind and helpful to others, be virtuous, meditate and cultivate ourselves to higher spiritual levels. Cheers.
I am astonished with how much detail you guys put into these videos with just an amazing cast knowledge you guys have over the entire human body. Amazing 🙌🏼🤙🏼💙
What a perfect and fantastic way to make this topic clear to everyone through pictorial and anatomy is the achievement of this video. Congratulations and keep it up!!!!!
I’m so glad you understand the dilemma of wanting/needing sunshine (especially for my mental health) but burning easily, requiring shade, sunscreen, etc., if I’m in the sun for more than 10 minutes. Sigh.
Eat a ten carrots a day and increase the sun expose five minutes per day and you'll tan without burning.
I was used to get burned within 15 minutes also, now I can stay for hours. Only thing I changed was my diet: no more refined seed oils, and low on carbs.
to keep from overheating, I sunbathe for 10-15 minutes at a time, only at UV over 4 (or else it's pointless) but under 8 (or else it feels like being microwaved) (your weather app lists the current UV) - and I cover my face with a hat because it burns easily and doesn't contribute much to absorption - supposedly this regimen once daily is enough for long-term results, wish me luck
It's the exact opposite fir me as a dark skinned person.I need to spend more time out there to get more uv in my skin.
That’s amazing! I’m 31 years old now and when I was a child, my mom used to make me sit under the morning sun drinking a glass of milk because my pediatrician recommended. I hated doing that back then but now I feel so grateful.
Morning sun is awesome, but the best time of the day to make vit d is actually around noon. Its the uv light that is you need and its strongest between 10 in the morning, 4 afternoon. The problem is its the same thing that makes skin cancer lol.
I just had an exam about human biology and one of the questions asked was about this exact topic. A little late for this video to get recommended to me, but this channel has helped me not only understand the human body more, but also become less squeamish, which was a big issue for me in the past. I still have a long way to go, but I'm happy with the improvements I've made so far. And I'm pretty sure this channel had a big part in it
When I was young I don't enjoy science class, but watching you explain everything I really love to learn more from you.
I have learnt about vitamin D3 and its process in human atonomy in my foundation class but no one has explained it so well like you did and now I understand it way better than before.Thank you for this video I will watch your other videos now 😊
This was an awesome video, I hope you guys do more videos on the internal organs like the liver, stomach, kidneys etc. or for example what a fatty liver can do to your body. Keep it up!
Yall are literally so cool. Your videos are always super interesting and easy to understand. I've learned more on this channel than I ever did in bio class
Love your videos guys, I've learned so much from this channel.
Please do a Vitamin K video?? (Actually, do all of them!) I knew Vitamin D was good for bone health, but I couldn't find an understandable explanation as to why. As you know, there is a growing interest in nutritional health on RUclips. Thank you for being intuitive & digestible
There is no useless Vitamin. You don't need a video for each single one. If they tell you, you do have a deficit, without having you testet, they just make you crazy. It's the same as telling you, you have cancer - Take a pill. They play with your fears.
Vit D3 + K2 go hand in hand together. I purposely increased dosage of vit D3 and ate vegetables rich in k2 for 2-3 months straight. My dentist said my gums and teeth dramatically improved and it was evident how strong they became
@@fahimashah4573 what vegetables did you eat?
@@beardednomad11 kale, spinach. Broccoli’s. Cheese, beef liver
Vitamin D also has an affect on mental health. Eg dark, cold times are more likely to cause depressive episodes too.
seasonal affective disorder
I'm a patient that not only had her thyroid removed but parathyroids were damaged. I'm vitamin D deficiency, i no longer make calcium so I have hypocalcemia, no thyroid so I'm hypothyroidism. Hypocalcemia is no joke I have been weeks in hospital getting bags of calcium iv, I have twitches in my face, my bones hurt bad, I have lost my teeth, and it's a hard disease. You never hear about people who suffer like me....
Stay strong.
God bless you
Excellent information. I lived in a mostly gray, cloudy region (during the winter) of the US for a few years and my Vitamin D levels be came very low. I had to take supplements. Then I moved to a mostly sunny region 7 years ago. I haven't taken supplements in over 5 years -- Vitamin D level are normal. Amazing!
I actually had a vitamin D deficiency from staying indoors due to the pandemic for 2 years!
Same
Man I'd be pissed if I went through all that just to find out they lied about the 'pandemic'
Makes me laugh when people use that word. I ask them to name one person that died and so many people can't. Not saying nobody died or that Covid isn't real, but our threshold for using the word "Pandemic" seems a little low.
On the channel Darkhorse, they had an interview a while ago with a couple who have spent years studying vitamin D, some of the facts they cover is quite amazing
An interesting fact is that sun exposure needs to be done at certain times of the day, basically when the sun is high, otherwise the exposure is mostly ineffective
Once again, another great video! Informative and educational, you guys are awesome! 👍
Thank you Jonathan 😊
Another wonderful lecture! I have learned so much from all your videos. You are my morning news every day!😍🙏
I would love to see your video on iron deficiency, on atopic dermatitis and risk of autoimmune diseases!
Thank you for your content ❤️
Great video! I already knew some bits here and there but your thorough coverage filled the gaps. Request: Vitamin K2 is often talked in conjunction with D3. Hope you could make a video on that too. 🙏
Thank you so much for the wonderful video. Keep the good work going 🙏🏼
Great illustration of how amazing our bodies are.Very well executed from delivery to the live presentation.Made me wanna watch to the end,which l sometimes struggle with 👏🏽👏🏽
Thank you for sharing ❤
Omg I absolutely absolutely love this channel. And what a coincidence, just today morning I wanted to learn about how exactly our bodies make vit D from sunlight and you guys released this video. Thanks!
The information you give in your videos is so interesting and useful. Thank you for sharing your knowledge 🙏
Wow, really well explained, love this channel!
The thing about textbooks or visual aid is that I couldn't imagine for some reason where everything was located in my own body or how they really looked like in real life, even mixing up the left side the right side sometimes 😂 I love your work so much! Fun and simple ways to explain the complexity and now I know how things look and where they are located exactly, yay 😁
Id like to see a video on brain aneurysms, how they occur what they can feel like and what exactly they can cause and how they can affect other areas. They've always been a mystery and honestly a bit scary to me
This is awesome information, THANKS!
Thank you for making these beautiful videos! very informative
I saw I had low Vitamin D from a blood test. I'm not sure if it's a symptom of vitamin D defienecy but my energy level was very low until I started taking D3 supplements.
Same
It IS a symptom.
It can also come from B12 deficiency.
I heard you should take vitamin D with vitamin k
My vitamin D levels were eight. I also have been diagnosed with narcolepsy. I’d love to see a video about the link between vitamin D and sleep.
Very good video as always! Thank you!
I liked you reviewing the material again on the whiteboard. Helped put it all together
Recently, some RUclips video producers have been utilizing short videos (usually under a minute or two) to mention topics and familiarize with those topics without going into great detail. Would be nice to create a short video about vitamin K2, it's relationship with vitamin D, and difference in MK-7 version versus others. If there is enough interest then perhaps a separate full length video in greater detail. I'm especially interested in how well it assists in decalcification within arteries and calcification on bones.
Very important video. My vitamin D level was at 33 and since I started supplementing with 4000 IUs per day it is now up to 49. I never knew how important D is.
Mine is at 10:((((
I take boron with transdermal magnesium it boost the vitamin d in my body and calcium.. i go inthe sun 3pm to 3pm to 4pm
D is very important.. heh heh **FARTS**
I read many papers on it, and one was about covid.... people with 50 in the blood had 0 chance of passing or getting super sick...
I don't take synthetic vitamins, i go in the sun for a hour around 3pm . I use magnesium, i take real iron, i don't take sulfate iron. If you have problem with pain bones look in to boron.
Always excellent content,thank you for enlightening us,
Always amazing content!
That’s was soo informative 👍🏼I work in the healthcare field 💉🩸 and I had no idea of how everything goes 🤝 !!! Makes soo much more sense! Thank you for sharing 😇🙋🏻♀️
Glad it helped! And thanks for watching!
On additional note: if you have severe vitamin D deficiency and need to supplement it in high doses, you need to monitor your calcium level in blood and urine, cause you're at risk of developing hiperkalcemia, which is dangerous.
Fat soluble vitamins are ADEK.
When taking Vitamin D3 it’s advisable to add about 120-180mcg of Vitamin K2/MK7 for every 5000iu of D3 this helps directs the calcium in the blood and soft tissues to the bones and teeth also prevents buildup of plaques in the heart arteries and along the kidneys.
I was in the sun all summer and my vitamin D was still low, it was 21.
@Troy Joseph if you have deficit, building it up will be slow and most likely need supplementation. Sun and food are great if you're stable on normal level.
Greatly explained, thank you so much!
I subscribed awhile back. I just love the quality of your videos. Content is cool too!
It's like gold for the immune system.
Love your videos 😄
When I told my friends that you do not actually get Vitamin D from sunlight (sun is not emitting Vit D 😅) , they were shocked and said then why does everybody say so . Now,I can share them this video for the detailed explanation .
Thank you
Thank you for watching! And I'm excited about your discussion with your friends!
Technically you may be right but your body will make vitamin D when exposed to the sun. It basically means the same thing.
Yeah! Vitamin D is a hormone. Our bodies MAKE hormones. And sunlight is what helps us do it to make "Hormone D".
I missed the detailed explanation... only noticed the explanation of how the body processes ingested vitamin D. Where in the video did he explain about the sun?
@@nonyabidness5708 I heard a commenter say you don't get vitamin D from the sun, and I believe that may be true but your body uses sunlight to produce vitamin D.
Great information, thanks I love the way you explained it was very helpful!
You do a great job at explaining things.
I'm suffering from Vit-D deficiency right now, as he said, I get tested very late, cause earlier I had no idea of Vit-D or so. Right now I've lower back pain, where the femur meets the waist bone. It's very painful for me to walk even a single step, even sleeping flat is very hard. I would suggest everyone out there, who's feeling a bit unhealthy to get checked early, It might save you the nightmare that I'm living with. Hope I recover soon. I forgot to tell that Vit-D makes you feel depressed also, so one more reason to get you blood tested ASAP.
I love watching your videos, you explain things so simply! I just wanted to ask is it safe to take Vitamin D supplements daily, as they get stored in the liver? I find taking Vitamin D supplements really helps to strengthen my immune system xx
The best way to do is to make a blood testing, take d3 for a 60/90 days and test again. Unless you are taking 50 000 units a day - the probability of you overdosing is not big. Most bodybuilders take around 4000 units daily. We are not very out in the sun anymore.
Great content, fantastic presentation! Well done.
I appreciate this channel so MUCH!! I am amazed by the human body, especially now that I have so much wrong with me LOL! I have learned of parts I never heard of before!! The greater momentum?? Wow!
In 2018 I was tested, and my results came back as 5ng/mL. I've been taking it daily since. I'm of Finnish heritage, so super pasty white, and I don't get out much due to fibromyalgia, so I don't get much sun. (plus I lived near Seattle for 15 years). I also have degenerative disc disease. I'm wondering if this all started due to low levels over time. Hard to know for sure though until more study is done.
Hi IOHA can you talk about exocrine pancreatic insufficiency and/or the pancreas/exocrine system in general. I was recently diagnosed and there's almost no information online. I'd like to actually see what's happening. Thank you.
Thanks for sharing this , I really learn something valuable out of it 😊 .
An amazing explanation mate.
I used to live in rainy gray Seattle and I also dealt with depression, and my blood work had a vitamin D level of 21! I started taking supplements and within a week I noticed changes. It was so weird that such a small change made such a difference, but I was grateful!
Use Omega 3 too for depression
@@Attlechief what are you talking about dude
Wow, this video is fantastic! Thank you so much! I subscribed. 😊
Can you possibly explain why the parathyroid would produce (slightly) too much hormone? I was just diagnosed with this (the secondary hyper parathyroidism). It is mild and my doctor wants to just keep an eye on it for now. I’m concerned because I already have advanced osteopenia (57 y.o. female, BMI 21). My kidney and liver labs are normal. Is there something I could be doing to influence the hyper parathyroid issue?
Really helpful, thank you for this video
Love your videos. I learn a lot from your videos. I take notes as you are talking, and often miss the medical or technical terms flashed on the screen.
I would like to see the terms remain on the screen for a much longer time, or maybe better, placed as a list in the notes below or both.
Love the white board summary here.
Really nice and informative video, always wondered how the d3 and calcium work together. I wonder if some day you guys can make a video talking about how probiotics affects your gut and general health. I'm Japanese and I was tough to eat "kimuchi" every day since the Bacteria in the "Kim" will help me absorb more nutrients and so have a stronger immune system. Keep the good work 💪
Simplified versions of explanations like these should be taught to all teenagers in high school in health class for when they're out on their own post schooling and should be mandatory along with economics.
Unless you can put numbers on it, like how many minutes sun exposure you actually need per day, for given amounts of skin uncovered by clothing, there is no point in teaching it - it's in practice meaningless. Especially when school kids are strongly taught that sun exposure leads to skin cancer and they must be fully covered or covered in UV blocking cream at all times in the sun. How do you expect them to resolve this dilemma when even doctors don't know.
Another amazing video!
Thank you so much for this bro 🙏🏼
Two things to remember, 1) D is not a "vitamin" it is a hormone regulator. and 2) always consume K2 as MK7 with D to prevent calcification in soft tissues. Otherwise, great video.
officially its not a hormone but yes the molecular structure of vitd and testosterone are very very similar
Exactly 😊
@@ja.almighty It is a hormone regulator, and also very similar to estrogen lowering it and preventing breast cancer.
Can we get examples or references. I want to know more.
@@MrPrincessdlow look up molecular structure of testosterone or estrogen and compare it with the molecular structure of vitamin d
I been vitamin d deficient for years and have been on vitamin d supplement for years it was never explained how it works and the importance thanks for the lesson👍 g'day from Melbourne ,Australia
And no-one ever told you to get out into the sun more often around noon.. That's bizarre, right?
@@Lamz.. australia has one of the highest rates of skin cancer in the world. you underestimate how much the sun can burn here especially in the summer.
@@thiswillnotdo6027 Don't let them scare you out of the sun, people need to be exposed to sunlight, it's essential, my friend. Just don't get burned. I didn't burn anymore after banning vegetable seed oils out of my diet, and most of the sugar and carbs. Not only me, hundreds of thousands of people doing low carb/ keto experienced the same thing. No burn, no cancer.
Thanks for the information .. really appreciate and enjoy your videos.
Thanks for summarising with a Flowchart in the end.
When I was a teen my vitamin D and my iron levels were extremely low. I’m not sure which one it was but one of the levels even was in the negative 😅
Only symptom I noticed was fatigue- which also didn’t get better after taking supplements even though my levels turned almost normal with time.
Take care ❤
I had foot surgery 4 weeks ago and my surgeon recommended I take Vitamin D and C to assist my bones in healing faster. It was a bit weird getting Vitamin D prescribed to me since I live in such a sunny city, but I luckily only have to take it once a week. The Vitamin C is a daily thing. I loved learning why I need it and how it works. Thanks!
If you wear clothes and work indoors you're almost certainly deficient
It would take a long time in the sun to get what a supplement will give you. Unless you’re a lifeguard out there for hours, ten minutes walking to and from the car isn’t going to do anything.
@@amazingsupergirl7125 exactly this. You need to be in the sun for HOURS
@@Jacob_Overby No you don't. It depends upon your skin tone.
A darker person would need 30-45 minutes not hours.
@@JTR253 I wasn't talking about them but ok
Wow this video is awesome!
I was always fascinated with human body and hungry for learning! Thank you so much for your work! I will be forever your enthusiast👏👏👏👏
I really love the addition of the whiteboard! Helps reinforce all of the steps clearly especially with so many long words lol
Very informative video, thank you!
I tested last year and had a very low level of vitamin D. When I started to research more about it, I was surprised to see that there are not so many food sources of vitamin D and most of them come from animals.
As a vegetarian, my options were limited, so I opted for suppliments. While doing the research, I also came across the 'dillema' between using sunscreen and the absortion of vitamin D from the sun. From what I read until now, the opinions are divided since there is no much data about whether the suncreen inhibits the absortion of vitamin D. Theoretically, that should be the case, that since the suncreen blocks the UV rays, the absortion of vitamin D should be inhibited.
I did not found many studies, but the ones I read conclusioned that using suncreen does not have so much impact on the absortion of vitamin D.
Could you explain more this topic? because I am still a little confused.
Thank you very much!
Sun screen isn't that effective at preventing cellular sun damage anyways. Just cover up with a hat or full body loose clothing.
And nothing wrong with getting some sun exposure with no sun screen.
@@user-p6-3561 that seems counterproductive, you cant get vitamin d through clothes
Should not apply sunscreen for the first 10 - 15 minutes of expsoure to the sun except for the face to prevent wrinkles. After that time period apply it right away, because when you pass that period of time your skin will stop producing Vit D3 due to sunburn, and sunburn leads to skin cancer.
Please remember when you try getting Vit D3 from the sun, you only should wear swimsuit. Topless and shorts only, face is exceptional, you can wear hat, sunglasses, or even apply suncreen on your face.
@@thiswillnotdo6027 i meant if you want protection from the sun use cloths and not sunscreen. it just isnt very effective
i think that you should get some voluntary fullbody sun exposure, with no sunscreen, whenever you feel like it.
Sunscreens are not very good at their job anyway. So if you put one and go in the sun for 8 hours - you will get your vit d. It depends on your life goals and where you live tho. If you are gonna be out all day and live somewhere sunny - put sunscreen for sure. And a hat. And comfy loose clothing.
I'm curious how vitamin K2 plays into this. Also, I've read that the angle of the sun has to be above 50 degrees for you skin to absorb and synthesize vitamin D.
That was so interesting! Thank you
Excellent content!
I moved from Venezuela to the Netherlands about 4 years ago, and even though I've never been a person who likes to sunbathe, I've found that even if I take vitamin D supplements everyday I still need one of those super charged doses for a few weeks once a year that can be prescribed by the GP. I don't think my Latin body is made for (or has adapted to) the Netherlands lack of sun.
It's true, dark skinned people have lots of trouble getting enough sunlight on the northern hemisphere. And the supplements are usually way too low to have an effect. Amazon sells higher concentrated D3 pills, like 10,000 and 20,000 IU.
How come you didn't move to Spain? 🌞
Brilliant video which explained the mechanism so well. Can you please comment on the benefits of K2 with Vit D3 and the assistance it gives to get the calcium into the bones. Thank you.
Good stuff. Thank you!

EDIT: I live in WA and work under artificial light so I take a supplement once a week and, thankfully, my levels are good. I take one higher dose pill a week because I will forget if I take it daily. I’m a bad patient 🤷🏼♀️
Can’t imagine artificial light being anything but damaging. I worked in a store, years ago, & everything that sat within 2’ of the lights would be faded & have to be discarded within two weeks time. It would even penetrate the bottles.
@@sunshine3914 Honestly it really hurts my eyes as well. Anytime I’m under fluorescent lighting my eyes get really red and dry and irritated and then people think I’m either high or I’ve been crying because people feel the need to point out other people’s appearance I guess. I’ve actually grown to be self-conscious about it because I wouldn’t want a nurse to care for me that looked high or that she just had a breakdown in the break room.
I studied this is high school D3 was my topic to research and it's cool to here the extent of it. And I always say I'm going outside to get some vitamin D3. I'm an architect but learning about the body is so fascinating.
Great video!!!
Great episode . Thank you
Yeah great presentation.
